The late pastor at my church prior to my present assignment had started the church in 1950, and served it for more than 50 years; he only slept 4 hours a night, and to him that was normal.
You knew this would happen, some moron would jump up and say that all you require is 4-5 hours.. It’s me.. surprise!
That is it, 4 hours and occasionally 5, tops.. My entire life I have had trouble sleeping, so now I take pills to get 4 hours.. yuck.
I do nap, 20-30 minutes mid day, and have done that forever.. I worked in the restaurant and hotel business 45 years, and fit right in with the long hours.. 7am-2am.. yup
